CLOSURE FOR VESSELS.

SPECIFICATION forming part of Letters Patent No. 766,604, dated August 2, 1904.

Application filed May 1, 1900. Serial No. 15,071. (No model.)

To all whom, it may concern:

Be it known that I, CHARLES H. J. DILG, a

citizen of the United States, and a resident of or stopper-ing vessels of small or ordinarysizc and of any suitable material-as, for example, metal cans; and it has for its object the provision of a closure of the kind set forth simple in construction, inexpensive to manufacture, and eiiicient in practical use.

To attain the desired end, this my invention consists in the construction, arrangement, and operation of parts herein set forth.

In order to enable my invention to be fully understood, 1 will proceed to explain the same by reference to the drawings which accompany and form a part of this specification, in

Figure 1 represents a view in section of a can made according to my invention, and Fig. 2 is also a view in section of another can in which my invention is embodied.

Like letters of reference indicate like parts in both views.

I have found it desirable to provide a closure for vessels made of suitable material, but

ordinarily of sheet metal, such as tin or gal-- vanized iron, and which may be used to contain either liquids or solids, and which are usually made cylindrical in form, with or without being provided with a handle or spout, and l have therefore constructed according to my invention an article of the class described embodying the preferred construction of parts and their mutual relationship, combination, and organization in a composite body or structure, as hereinafter described.

teferring particularly to the drawings, A denotes the body of a can, the upper portion A of which is provided with a preferably perforated outlet or discharge opening, the upper part of which can may be made in ornamental form and also somewhat smaller in diameter and also exteriorly ScreW threaded at the end thereof, so as to engage with a closure, as the threaded or spirally-grooved cap B. The lower portion of the body A may be formed with peripheral head a, and the said can is also constructed primarily with an open end or bottom portion, the rim or edge of the same being relatively straight or vertical or in plane with the body of the vessel.

The independent bottom member of my can consists of an independent or secondary closure and cap 0, preferably made of sheet metal and consisting of a dish-shaped body C, having a marginal flange formed by the wall of the cap being turned at an angle and then turned upon itself to form an approximately U-shaped groove to serve as a seat for the edge of the body member or vessel or can, thus forming an inclined edge or rim. The closure or cover C thus has a groove formed with two parallel walls or bearing portions of different inclinations than the can-wall and is constructed and arranged to contact both faces of the body of the can A the entire depth of the groove, the opening of the groove being of the same width as the thickness of the can-wall and also coinciding or registering with the edge of the said wall, whereby upon application of the cover to the can the edge of the latter is forced out of its normal plane position and all motion or sliding movement of the cover is made impossible and a tight self-locking joint is formed and the parts are rigidly and permanently fastened together.

In cases where the can is filled with solids the bottom or closure cap C is simply pressed or sprung upon the lower end of the charged can A, the said cap being thereby rigidly and undetachably fastened to the body member of the can.

It is manifest that various omissions of some particulars could be made without materially aflecting the essential features of my invention or the operation of the remaining parts, and I do not therefore wish to be limited to the specific structural details of the organi- Zation herein set forth. Obviously the elements of the structure described may be located at an angle to the plane in which they are shown. 1 therefore use the words horizontal, vertical, and the like in a relative sense. The said cap 0, which after being once applied is non-detachable, may not only be formed, as in Fig. 2, with a concentric flange extending in an upward direction, as at and in a downward direction, as at (3*, but it may also be provided, if desired, with a detachable portion or secondary closure C having a rim to engage the flange C, whereby the secondary closure C may be secured to or detached from thecover, the object of the secondary or detachable closure (1 0f the nondetachable bottom 0 being to be usable in cases where, after the cap or cover is once applied, the can is intended to be recharged a number of times after the contents have been used from time to time by being caused to pass through the perforated portion of the top A.-

Obviously my closure device is applicable to be and may be used in connection with many kinds of containing vessels, and I do not therefore wish to limit myself to the use of my device in connection with cans alone.

It will be observed that my closure C, in connection with my can A, forms, essentially, a non-refillable vessel.

As it is evident that many changes in the form, construction, proportion, and relative arrangement of parts might be resorted to Without departing from the spirit and scope of my invention, I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described, but that such changes and ekcl uivalents may be substituted therefor, and t at IVhat I claim as my invention is 1. A can provided with a cover having a groove formed with two parallel walls or hearing portions of diflerent inclination than the the can the entire depth of the groove, the v opening of the groove being of the same width as the thickness of the can-wall and also coin.

ciding or registering with the edge of the said wall, whereby upon application of the cover to the can the edge of the latter is forced out of its-normal plane position and all motion or sliding movement of the cover is made impos sible and a tight self-locking joint is formed.

2. A can provided with a cover having a groove formed with two parallel walls or bearing portions of different inclination than the said can-wall and constructed and arranged to contact both faces of the body of the can the entire depth of the groove, the opening of the groove being of the same width as the thickness of the can-wall and also coinciding or registering with the edge of the said wall, whereby upon application of the cover to the can the edge of the latter is forced out of its normal plane position and all motion or sliding movement of the cover is made impossi ble and a tight self-locking joint is formed, the said cover being also provided with another flange, in combination with a closure provided with an edge or rim to engage the last-named flange and to be thereby secured to and detached from the cover at will.

In testimony of the foregoing specification I do hereby sign the same, in the city of New York, in the county and State of New York, this 27th day of December, A. D. 1899..
